In a contracting situation, you are told from the beginning that you work for your contracting company-- not for the company you are working at. As such, your contracting company (in this case, Randstad) is supposed to be on your side in business negotiations. Right? Wrong.
From the beginning I was lied to about compensation (including overtime, which my contract stated I should receive but they came back and redacted that part). This continued throughout the duration of my employment at Randstad-- they would contact my managers at my company behind my back, renewed my contract without letting me know, gave me an incorrect wage for weeks without resolution, consistently removed my manager from being CC-ed on important emails, and lied to my face about trivial matters.
I wasn't even asking for a lot from them. Some contracting companies have people reach out to you once a month to check up, or take you to lunch, or give you a small gift around the holiday. I don't really care for the frills (which were not provided)-- I wasn't even on their insurance. I just want to be able to (1) work and (2) get paid correctly and on time.
The director of my program had a knack for slathering you with sickeningly sweet compliments in order to keep you from escalating issues, and to put off having to answer any questions related to contracts or pay-- you know, the two reasons you work for them to begin with. Oh, you heard my manager is super pleased with me and loves the work I'm doing for them? That's great, I already knew that... please just answer the question I asked, thanks.
The lack of transparency in their business dealings, as well as the lack of competency in performing the most basic of tasks, led me to leave the company. The manager I worked under was equally disgusted by the lack of professionalism from Randstad.
Also, within 2 months I had gone through 3 Randstad account managers-- everyone had left, and their employee turnover rate was incredibly high. If that doesn't say something about a company, I don't know what does.
